Admittedly the definition is hard to pin down but clearly the thing exists or the word wouldn’t have taken off so quickly.

Roughly, it refers to the worldview in which group power dynamics are all-determining, where race is destiny, where the individual takes a back seat, and where the only possibly solution is some form of reverse discrimination - but even that will never work, really, because injustice is destiny.

It exists, quite few people believe these things, far far more of them hate it, and that’s why the peak woke moment seems to have passed. Mercifully.
